<h1>2012 marked the “The Twenty First International Obfuscated C Code Contest”</h1>

<h2>Standard IOCCC stuff</h2>
|
|
|
|
|
|
|
|
|
|
<p>The IOCCC has a web site and now has a number of international mirrors.
|
|
|
|
|
The primary site can be found at <b>www.ioccc.org</b>.
|
|
|
|
|
|
|
|
|
|
<p>Use make to compile entries. It is possible that on non-Un*x / non-Linux
|
|
|
|
|
systems the makefile needs to be changed. See the Makefile for details.</p>
|
|
|
|
|
|
|
|
|
|
<p>Look at the source and try to figure out what the programs do, and run
|
|
|
|
|
them with various inputs. If you want to, look at the hints files for
|
|
|
|
|
spoilers - this year we included most of the information included
|
|
|
|
|
by the submitter.</p>
|
|
|
|
|
|
|
|
|
|
<p>Read over the makefile for compile/build issues. Your system may require
|
|
|
|
|
certain changes (add or remove a library, add or remove a #define).</p>
|
|
|
|
|
|
|
|
|
|
<p>Some ANSI C compilers are not quite as good as they should be. If
|
|
|
|
|
yours is lacking, you may need to compile using gcc instead of your
|
|
|
|
|
local compiler.</p>
|
|
|
|
|
|
|
|
|
|
<h2>Remarks on some of the entries</h2>
|
|
|
|
|
|
|
|
|
|
<p>We believe you will be impressed with this year’s winners. We had
|
|
|
|
|
a very difficult time picking a single best from among the other winners
|
|
|
|
|
because the overall quality of the winners were so high.</p>
|
|
|
|
|
|
|
|
|
|
<p>This year we selected the top 4 entries for particularly high honors:</p>
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
<li><p>Gold award - Balanced use of obfuscation</p>
|
|
|
|
|
|
|
|
|
|
<p>A very extremely subtle and twisted piece of source code!
|
|
|
|
|
Even if you start with the zeitak_deobfucate.c source,
|
|
|
|
|
you will still have a very challenging time to understand it!</p></li>
|
|
|
|
|
<li><p>Silver award - Most elementary use of C</p>
|
|
|
|
|
|
|
|
|
|
<p>A fun program that could also have won “Best abuse of
|
|
|
|
|
Ghostscript” because it managed to create some PDF files
|
|
|
|
|
that Ghostscript could not read.</p></li>
|
|
|
|
|
<li><p>Bronze award - Best use of cocoa</p>
|
|
|
|
|
|
|
|
|
|
<p>A picture within a picture is worth more than a
|
|
|
|
|
thousand (4 byte) words. :-)</p></li>
|
|
|
|
|
<li><p>Honorable mention - Most complex ASCII fluid</p>
|
|
|
|
|
|
|
|
|
|
<p>When you see this program in action, you too will
|
|
|
|
|
very likely say <a href="http://bit.ly/R6ALpK">wow</a> as we did!</p></li>
|
|
|
|
|
</ul>
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
<p>But don’t ignore the other winners! There are games, utilities,
|
|
|
|
|
eye candy, calculators and graphical tools to explore.</p>
|
|
|
|
|
|
|
|
|
|
<p>This year, Yusuke Endoh won with two entries, one of which (endoh1)
|
|
|
|
|
won the special Honorable mention award. Eight of the winning entries
|
|
|
|
|
were from people who won in previous years.</p>
|
|
|
|
|
|
|
|
|
|
<p>This year we had a number of winners from Asia. We saw our second
|
|
|
|
|
winner from China and first from Korea. We are pleased to see
|
|
|
|
|
outstanding entries from areas of the world that have not been
|
|
|
|
|
active in past contests. Will we see an upswing of entries
|
|
|
|
|
from South America, Africa and Antarctica next year? :-)</p>
|
|
|
|
|
|
|
|
|
|
<p>Please note that judging is done completely anonymously. Please
|
|
|
|
|
do NOT reveal your identity in your source code. In the future we
|
|
|
|
|
may disqualify entries that reveal the identity of the submitter!</p>
|
|
|
|
|
|
|
|
|
|
<p>There were some outstanding entries that did not win. Unfortunately
|
|
|
|
|
some very good entries lost because they:</p>
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
<li><p>would take years to execute</p></li>
|
|
|
|
|
<li><p>were way way oversize and didn’t even attempt to justify their
|
|
|
|
|
excess by a clever abuse of the rules</p></li>
|
|
|
|
|
<li><p>obfuscate themselves by simply invoking a complex
|
|
|
|
|
state machine</p></li>
|
|
|
|
|
<li><p>depend on a single obfuscation trick</p></li>
|
|
|
|
|
<li><p>could only be run on a particular vendor’s platform</p></li>
|
|
|
|
|
<li><p>were very similar to previous winners</p></li>
|
|
|
|
|
<li><p>were based on an overused theme such as yet another
|
|
|
|
|
fractal display program</p></li>
|
|
|
|
|
<li><p>didn’t work as documented</p></li>
|
|
|
|
|
</ul>
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
<p>We hope the authors of some of those entries will fix and re-submit
|
|
|
|
|
them for the next IOCCC.</p>
|
|
|
|
|
|
|
|
|
|
<p>There is a risk in submitting an entry that is similar to a well
|
|
|
|
|
used theme by previous winners. Previous winners set a very high
|
|
|
|
|
bar. A new winner must not only compete against other submissions
|
|
|
|
|
form the current year, they must also excel over similar winners
|
|
|
|
|
in some particularly impressive way.</p>
